304 Ah of power is quite a bit. The batteries are 38 Ah each and weigh around 25lbs each. I've crunched the numbers and yes, for a weekend warrior camping trip I wouldn't come close to needing that much. For a few weeks off the grid in the winter, 304 Ah is going to be great. With full sun in the summer the solar panel will help replace some of the power as I use it. In the winter with short overcast or snowy days the panel isn't going to help much...
304 Ah should also be good for running power tools on my ranch without having to fire up a generator.
When I'm not doing military stuff I'm a metal smith/artist. It's going to be great having 304 Ah of quiet, clean, semi-renewable power available to run lighting, video and media equipment, fans and whatever else during those long weekend art shows....
The batteries have a good power to weight ratio. I could pull some out for short weekend trips and put them back in for longer adventures, ranch work, or art shows, but that's silly. The trailer is good sized with a 4'x8' floor. It weighs in around 1100 lbs with batteries under the floor. That leaves me with 2400 lbs of weight carrying capacity. It pulls very well, although I've never loaded it even close to max capacity. So for now, I'm sticking with 304 Ah. Once I get the wiring all figured out, fuse box, charge controllers, lighting, 12v power outlets, inverters, and then do a few long trips and art shows with it I can adjust fire as needed. The way the batteries fit under the floor I can fit 6 together into one bank, then I have 2 that have to go into a separate compartment. I was thinking of just pulling the 2 batteries that don't fit in the bank, but figured that since I already have them I may as well use them. So it's either 304 Ah at about 200 lbs, or 228 Ah at about 150 lbs.
